M16 Camera Manual: Operating The Camera
3.3.3 Inserting a Filter
MOBOTIX oers a polarization lter in its range of accessory products for all sensor modu-
les (except the B016). The polarization lter prevents unwanted reections from smooth
surfaces. The lter can be used to provide better facial recognition of the people behind
the windshield of a car, for example. Only one lter can be used per sensor module, which
then replaces the standard protective glass lens.
Procedure
1.
Position the blue lens wrench on the notches of the
protective glass lens. Rotate the wrench tothele
until you feel a stop (max. 300°) and then a little bit
further until the protective glass lens slides out of
the sensor module.
2.
If required, clean the inside of the lter using a clean,
lint-free cotton cloth.
3. Place the lter on the notches of the blue lens
wrench.
4.
Position the lter with its clips over the two recepta-
cles on the sensor module (red arrow on the image
in the margin) and rmly press onto the sensor
module. Rotate the glass to the right using the
blue lens wrench until you feel a stop.
5. Adjust the polarizationlter according to the camera’s live image on the computer
monitor. Rotate the lter to the le using the blue lens wrench until you reach the
desired setting (maximum 180°).
6. To readjust the polarization lter, rotate it back to the right until you feel a stop
and repeat step 4.
7. If required, clean the outside of the lter using a clean, lint-free cotton cloth.
Note
Note that using the polarizationlter reduces the amount of light that enters the lens
by approximately 50 %.
